application filed March 7, 1924. Serial No. 697,432.
To all whom 'it may concern:
Be it known that l, lsanon RUDOLPH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements 1n Radiocabinets, of which the following is a specification.
My invention relates to radio cabinets and more particularly to cabinets of the portable type. The objects are to provide a compact cabinet which will house a radio receiving unit, a loud speaking recorder, thevbatteries for the receiving unit and the loud speaker, and the aerial; which will be so constructed that access to the interior of the receiving unit, the batteries and their connections may be readily had, and which will have the lid of the cabinet so arranged that it may be used to regulate the volume of sound from the loud speaking unit.
These objects, and other advantageous ends which will be. described hereinafter, I attain in the following manner, reference being had to the accompanying drawings' in which- Figure 1 is a perspective view of a radio cabinet constructed in accordance with my invention,
Figure 2 a perspective view of the cabinet shown in Figure 1 illustrating the rear of the same in an open position,
Figure 8 a View similar to Figure 2 illustrating the front of the cabinet in an open position,
Figure 4 is an enlarged section on line l--l of Figure l, and
t Figure 5 a section on line 5 5 of Figure 4.
Referring to the drawings, 1 indicates the body of a cabinet having a back 2 hinged to its rear at 3 and a lid 4 hinged to its front at 5. The hinges are preferably of the detachable type. The body is provided with a partition 6 forming two compartments 7 and 8. Compartment 7 receives a receiving unit 9 and compartment 8 receives a loud speaking unit 10. The rear of the body 1 Within compartment 7 is provided with an opening 11 through which access to the interior of the receiving unit may be had. Back 2 is provided with a partition 12 forming compartments 13 and 14. Compartment 13 houses high voltage batteries 15 and comk partaient 14 is provided with shelves 16 for supporting low voltage batteries 17. The connections from the batteries td 'the receiving. unit are'made through Kopening 9 as shown in Figure 2.7 Lid 4 is provided With a partition 18 substantially in the same 60A other accessories. Back 2 and lid 4 are locked 65 to the body by any suitable catch preferably as shown at 22. The back `has binding posts 23 on its outside for the aerial and ground connections. A handle 24 of any suitable construction is secured to the top of the body by bolts 25 or otherwise.
To install the receiving unit and loud speaking unit in the body, the receiving unit. is slipped into compartment 7 and secured therein and the loud speaking unit 10 is 75 slipped into compartment 8 and secured therein. The electrical connections between the receiving unit and the loud speaker are then made. Batteries 15 and 17 are placed in back 2 preferably in the manner shown 80 in Figure. 2 and the electrical connections between the batteries and the binding posts of the receiving unit are made through open` ing 9 as shown in Figure 2. The aerial and ground are also connected to their respective 95 vbinding posts 23 which are electrically con nected to their corresponding binding posts on the receiving unit. The back vis then locked to the body by a catch 22 and the receiving unit is ready for tuning in broadcast matter. After the receiving unitI is tuned in and music is heard from the loud speaking unit, the volume of the music may be regulated by opening or closing lid 4 to a greater or less extent. After use, the
aerial and ground connectionsv may be disconnected and placed in thefgompartment 20 and the lid closed and locked to body 1 by catch 22. The complete radio outlit is thus compactly enclosed in a cabinet and may 1o be conveniently carried to any desired place.
While l have described my invention as taking a particular form, it will be' understood that the various parts may be changed without departing from the spiritthereof,
and hence I do not limit myself tothe precise construction set forth, but consider that l am at liberty to make such changes and alterations as fairly come Within the scope of the appended claims.
